green, co-founder of the progressive change campaign says -- yesterday on abc's "this week" congressman keith ellison squared off on the issue with former obama economic at visor steve rattner. >> there has to be a compromise, $16 trillion deficit, you're not going to solve all that with tax increases or discretionary cuts. we can talk about how we do it -- >> get specific, steve, because when you start talking about fixing the entitlement program, we're clear, social security is off the table. >> we're not clear. no. >> no. what secretary geithner has said on a separate process. >> eric, we've talked to some degree about the back and forth within the republican party on this deal but haven't spent as much time on what's happening on the left in terms of what the democrats will stomach in terms of entitlement reform if any at all. do you think there is a wing of the party that believes that this process can happen without reform on entitlements? >> no. i don't think anybody who's seriously in the game thinks that. i think the question is, how much do you have to give up, is it reasonable? wha
